Yes, I've had that happen. You can click Submit and, when the computer is slow, it really doesn't appear that anything is happening, so then you click it again and you get a double post. You don't want to leave because every once in while nothing did happen
and then you would lose your post. Everyone understands, don't worry. Delete it if you can, if not then no one is bothered. If it happens to you alot, then you must be clicking twice routinely because it seems slow---so yep, just click once and wait and see if you find a difference. In fact, maybe you feel you should click twice, since one does on many occasions have to click twice. So, just click once. I'm sorry for this terrible explanation.
Welcome to the forums. Some of us are a bit wack-o!
